Vhile the drawings illustrate an cmbodimentof the invention it is to be understood that in adapting the same to meet different -conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application,

Figure l is a front View illustrative of the invention,

Figure 2 is a top plan view of the parts shown in Figure l,

Figure 3 is a sectional detail of the indicator and operating mechanism,

Figure 4: is a detail perspective view of the hand wheel for operating the signal and the detent in cooperative relation therewith,

Figure 5 is a sectional detail ofthe indicator, and

Figure 6 is a extension of the supporting arm and shaft showing the hand wheel in section.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The numeral 1 designates an arm having detail view of the 'innerV a clamp 2 at its inner end for attachment to the frame of the windshield of a motor vehicle or other convenient part of the machine, said arm having an inner extension rearwardly. The indicator 5 ismounted to 1 turn inta vertical plane, whereby to point laterally in either direction to designate the .intention to turn to the right or to the left, or to point upwardly or downwardlyv to indicate the intention to go straight ahead or to stop.
